North Kent County Exposure Assessment: Results
North Kent County Exposure Assessment Participant Demographics and Serum PFAS Summary
This is a high-level overview of results from the first report of the North Kent County Exposure Assessment (NKCEA). In the report, the Michigan Department of Health and Human Services (MDHHS) compared the PFAS blood levels of NKCEA study participants with the PFAS blood levels of people whose data is included in the National Health and Nutrition Examination Survey (NHANES). NHANES is a program of the Centers for Disease Control and Prevention (CDC). It provides estimated levels of some environmental chemicals in the general U.S. population.
NKCEA participant PFAS serum levels varied by type of PFAS, and ranged from low levels (similar to levels found in many people of the U.S.) to high levels that exceeded what is commonly found in most people in the U.S.
Participant Demographics and Serum PFAS Summary Report: Report 1 of the North Kent County Exposure Assessment
This report offers an in-depth look at the participant demographics and levels of 30 PFAS found in the blood of people 12 and older who took part in the North Kent County Exposure Assessment (NKCEA). Michigan Department of Health and Human Services (MDHHS) compared the PFAS blood levels of NKCEA study participants with the PFAS blood levels of people whose data is included in the National Health and Nutrition Examination Survey (NHANES).

Drinking Water PFAS Concentrations and Exposure Factors Influencing Measured and Predicted Serum PFAS Concentrations: Report 2 of the North Kent County Exposure Assessment
This second report for the North Kent County Exposure Assessment (NKCEA) discusses several important findings. For most NKCEA participants, residential drinking water wells were a major source of PFAS. However, some participants had low levels of PFAS in their drinking water but still had PFAS in their blood, indicating that these participants had been exposed from one or more source(s) other than drinking water. Significant predictors for increased PFAS levels in study participants were:
- Estimated daily intake of PFAS from drinking water.
- Increasing age.
- Male sex.
- Eating any wild-caught fish.
